Is stage 1 squamous cell carcinoma serious?

All types of cancer are serious, but fortunately, stage 1 squamous cell carcinoma is quite treatable and is rarely fatal. At this second stage, squamous cell carcinoma is almost always successfully treated because it's still confined to the skin. However, if it's left untreated, the cancer may advance and can spread throughout the body, making it more difficult to treat. Because early diagnosis and treatment usually results in a successful recovery, it's important to talk to your doctor as soon as you notice any symptoms of stage 1 squamous cell carcinoma.
